1. INTRODUCTION

The 86431 Power Unit is one of the family of units in the GE Multilin’s JungleMUX SONET and T1 Multiplexer (T1MX) digital transport/access systems designed specifically for the requirements of the utility (Power, Transportation, Pipelines, Oil & Gas, etc.) industry using optical fiber transmission.

This manual explains how to operate, install and maintain the Power Unit.

There are two generations of Power Units for JungleMUX multiplexers; the old-generation (B)86431-0X units and new-generation B86431-4X units. The two units implement completely different hardware solutions. The descriptions and block diagrams for both generations of units are included.

Engineering documentation includes EAS schematics for all unit circuitry. Related Publication and Documentation Support

Additional information is provided in the JungleMUX Technical Overview and Reference Manual for system planning and engineering. The user may also find useful information in Technical Practice and Installation Manuals (TPIMs) for other JungleMUX units.

Customer inquiries for information contained in this manual should be directed to JungleMUX Product Line Management. GE Multilin appreciates notification of any possible errors or omissions contained herein.

Shipped with all purchased JungleMUX SONET and T1MX nodes is a Node Assignment Drawing (NAD), which provides necessary configuration details for the units and shelf location. Product Color and Nomenclature

The JungleMUX product line has undergone a transition to a new colored package. To distinguish between legacy gray and new black, a "B" prefix is added to all black shelf and unit code numbers to identify the item color. Note that there is no functional difference between gray and black versions of individual module types sharing the same code numbers as there is no difference in their internal electronics/hardware. Note that the gray colored modules were discontinued in June 2008. The modules added to the product portfolio after November 2007 have been available in black only.



Handling and Packing Equipment with Electrostatic Discharge Sensitive (ESDS) devices or components must be shipped in protective containers and necessary handling precautions observed; otherwise, all warranties, expressed or implied, will be considered null and void. The following Electronic Industries Association (EIA) attention label appears on all GE Multilin EAS schematics and should be attached on all containers used for ESDS items to alert personnel that the contents requires special handling.

2. UNIT OVERVIEW

The 86431 Power Unit provides the interface between the customer-supplied station battery and a JungleMUX node. The unit’s input voltage requirement can be 24, 48 or 130 VDC depending on the unit option (refer to Section 8: Ordering Information for more information). The unit provides power supply to the shelf’s 5 VDC power bus. Normally, two Power Units are paralleled on the same shelf to provide redundancy in the case of a single Power Unit failure. If necessary, an additional (third) Power Unit can be installed in the shelf. The power buses of multiple shelves belonging to the same JungleMUX node can be paralleled (refer to the 86430 Equipment Shelf TPIM). It is strongly recommended that no more than six Power Units be paralleled. The old-generation (B)86431-0X Power Units can sustain a maximum load of 18 W while the new-generation B86431-4X Power Units can sustain a maximum load of 30 W on permanent basis. The (B)86431-0X and B86431-4X units are compatible and can be paralleled along the same power bus.



3. FRONT PANEL LAYOUT

(B)86431-0X Power Unit A front panel layout for a (B)86431-0X unit is shown in Figure 1 (the figure specifically shows the layout for the 130VDC option). The Power Unit does not come equipped with a CI (Craft Interface) since there are no software-adjustable parameters.

Alarm LED (Red) This LED provides a visual indication of the unit's status. The LED will light in a protected system (i.e. two or more Power Units in parallel) if the fuse opens or the station battery is removed. The LED will also light if the internal DC-to-DC converter fails.

Fuse The (B)86431-0X unit uses a fast-acting GMT fuse in line with the main battery input. The fuse protrudes through the faceplate so it can be installed or removed from the front. The fuse rating depends on the unit option as shown in the table below.

Unit Option Fuse Rating

(B)86431-01 (24V) 2 A

(B)86431-02 (48V) 1 A

(B)86431-03 (130V) 0.5 A

Extractor Located at the bottom of the unit's face plate is the extractor, which is an integral part of the unit's casing. As the name implies, it allows for easy extraction of the unit from the shelf.

WARNING

Do not use the extractor to force the unit into the shelf as this could

result in damage to the extractor.

4. UNIT DESCRIPTION

The 86431 Power Unit provides the regulated +5 V required for the JungleMUX shelf by converting station battery input to +5 VDC. The unit can interface various station battery inputs depending on the unit option. All customer connections for station battery input and alarm reporting are made on the interconnect paddleboard. Block diagrams for the (B)86431-0X and B86431-4X units are provided for reference purposes in Figure 3 and Figure 4, respectively. The user should refer to EAS-86431-M1 and EAS-86431-4X for complete circuit schematics. (B)86431-0X Power Unit Station battery is applied to TB1 of the paddleboard and fed to the unit via backplane connector J1. After being filtered from RF by L1, L2, C1, C2 and C3, the input DC power is sent to the DC-DC converter U1 (Vicor). The converter is an isolated DC-DC switching converter to allow operation from a floating station battery input. +5.35 VDC (measured at low loads) is applied to the shelf on J1(A12, C12) and shelf ground on J1(A13, C13). The low voltage detector U2 lights the Alarm LED which is powered from the shelf power bus if a second power unit is installed on the bus. Alarm relay U3 will provide a Form-C contact upon failure of U1 or absence of station battery. The NO contact is open when the alarm relay is energized and the unit is operating normally.1 B86431-4X Power Unit Station battery is applied to TB1 of the paddleboard and fed to the unit via backplane connector J1. After being filtered from RF by L1, C1, C2, C3, C4 and C21, the input DC power is sent to the DC-DC converter U2 (Glary). The converter is an isolated DC-DC switching converter to allow operation from a floating station battery input. +5.25 VDC (measured at output power of 15 W) is applied to the shelf on J1(A12, C12) and shelf ground on J1(A13, C13).

1 The NO contact is available on all versions of the 86431-90 Power Unit paddleboard. The NC contact was available on 86431-90 paddleboard versions MS ISS 91X and MS ISS 1.



The low voltage detection circuitry turns the Red LED on (and Green LED off). The Red LED is powered from the shelf power bus if a second power unit is installed on the bus. Under normal conditions, the Green LED is on and Red LED is off. The low voltage detection circuitry also drives the Form-A alarm relay U7 and sets the contact into alarm state (contact closed) upon failure of U2 or absence of station battery. The contact is open when the alarm relay is energized and the unit is operating normally. The overvoltage protection circuitry is a backup for the primary overvoltage protection built in the converter module U2 itself and it is set to trigger a few tenths of a volt higher than the primary feedback system. It would activate only in the unlikely event of the primary feedback failure thus preventing uncontrollable rise of the output voltage. If an overvoltage condition is detected by the secondary feedback circuitry, the converter module’s PC input (U2(2)) is driven low which forces the converter into permanent shutdown state. This condition causes the undervoltage detection circuitry to light the Red LED and turn the Form-A contact into alarm state. The converter module can then be reset only by power cycling the unit; however, the unit must remain unplugged from the shelf for at least 2 seconds.

5. INSTALLATION

This section provides information for installing an 86431 Power Unit. All JungleMUX nodes are shipped with Power Units installed as per the Node Assignment Drawing for the node. The Power Unit does not have any configurable parameters and therefore no software programming is required.

CAUTION

The 86431 Power Unit has ESDS components and therefore standard static

protection precautions should be observed when handling, packing or

shipping the unit.

Pre-installation Visually check the unit for damage. Ensure that the jumper P2 (applicable to B86431-4X units) is in Normal position and the screws are in place and firmly tightened. Keep the shipping containers and packing materials for future use. If a unit is damaged, file a claim with the shipping agent or the local GE Multilin representative. Shelf Position The Power Units are normally installed in both the 1st and 15th shelf slots of each JungleMUX shelf. Power Units are paralleled so in the event of single unit failure the shelf power is maintained. If necessary, an additional (third) Power Unit can be installed in the shelf. The power buses of multiple shelves belonging to the same JungleMUX node can be paralleled (refer to the 86430 Equipment Shelf TPIM). It is recommended that no more than six Power Units be paralleled. A typical rack layout is shown in Figure 5.
